Cannot use 'import.meta' outside a module on 0.36.0 (not 0.34.0)

[frbuceta]

I just updated from version 0.34.0 to 0.36.0. In version 0.34.0 it works perfectly.

ncc: Version 0.36.0
ncc: Compiling file index.js into CJS
...
esm_dirname = (0,external_url_.fileURLToPath)(import.meta.url);
                                                       ^^^^

SyntaxError: Cannot use 'import.meta' outside a module

source:

import { fileURLToPath } from "url"

fileURLToPath(`${import.meta.url}/../somestaticfile.txt`)

compile with 0.34.0:

import { createRequire as __WEBPACK_EXTERNAL_createRequire } from "module";
/******/ /* webpack/runtime/compat */
/******/ 
/******/ if (typeof __nccwpck_require__ !== 'undefined') __nccwpck_require__.ab = new URL('.', import.meta.url).pathname.slice(import.meta.url.match(/^file:\/\/\/\w:/) ? 1 : 0, -1) + "/";
/******/ 
/************************************************************************/
var __webpack_exports__ = {};

;// CONCATENATED MODULE: external "url"
const external_url_namespaceObject = __WEBPACK_EXTERNAL_createRequire(import.meta.url)("url");
;// CONCATENATED MODULE: ./src/index.js


(0,external_url_namespaceObject.fileURLToPath)(`${"file:///project/home/imyelo/workspace/src/index.js"}/../somestaticfile.txt`);

compile with 0.36.0:

import { createRequire as __WEBPACK_EXTERNAL_createRequire } from "module";
/******/ /* webpack/runtime/compat */
/******/ 
/******/ if (typeof __nccwpck_require__ !== 'undefined') __nccwpck_require__.ab = new URL('.', import.meta.url).pathname.slice(import.meta.url.match(/^file:\/\/\/\w:/) ? 1 : 0, -1) + "/";
/******/ 
/************************************************************************/
var __webpack_exports__ = {};

;// CONCATENATED MODULE: external "url"
const external_url_namespaceObject = __WEBPACK_EXTERNAL_createRequire(import.meta.url)("url");
;// CONCATENATED MODULE: ./src/index.js


(0,external_url_namespaceObject.fileURLToPath)(`${import.meta.url}/../somestaticfile.txt`);

seems like webpack doesn't convert import.meta.url staticly in ncc ^0.36.0

Thanks for this! I had to downgrade all the way from 0.38 to make this work 🤷🏽‍♂️

I just ran into the same issue, and downgrading to 0.34.0 worked for me as well.
What a coincidence that we run into the same issue just 8 hours apart, when it's been inactive for a year!

Has there been a workaround found for this issue? I managed to pinpoint the problematic import.meta.url inside one of my dependencies. Removing it solves the issue but also downgrading to 0.34.0 solves it. Is it possibly this change which is causing this issue?
